c6c2f0fd78 Implement SequenceLocks functions
SequenceLocks functions are used to evaluate sequence lock times or heights per BIP 68.

The majority of this code is copied from maaku in #6312

114b581 Prevector type (Pieter Wuille)

eece63fa72 Switch blocks to a constant-space Merkle root/branch algorithm.
This switches the Merkle tree logic for blocks to one that runs in constant (small) space.
The old code is moved to tests, and a new test is added that for various combinations of
block sizes, transaction positions to compute a branch for, and mutations:
 * Verifies that the old code and new code agree for the Merkle root.
 * Verifies that the old code and new code agree for the Merkle branch.
 * Verifies that the computed Merkle branch is valid.
 * Verifies that mutations don't change the Merkle root.
 * Verifies that mutations are correctly detected.

391dff16fe Do not store Merkle branches in the wallet.
Assume that when a wallet transaction has a valid block hash and transaction position
in it, the transaction is actually there. We're already trusting wallet data in a
much more fundamental way anyway.

To prevent backward compatibility issues, a new record is used for storing the
block locator in the wallet. Old wallets will see a wallet file synchronized up
to the genesis block, and rescan automatically.

Exempt unspendable transaction outputs from dust checks
Since unspendable outputs can't be spent, there is no threshold at which it would be uneconomic to spend them.

This primarily targets transaction outputs with `OP_RETURN`.

5a7304b69d Move recently introduced CTransAction::IsEquivalentTo to CWalletTx
CTransAction::IsEquivalentTo was introduced in #5881.
This functionality is only useful to the wallet, and should never have
been added to the primitive transaction type.

b2b3619262 Implement CTransaction::IsEquivalentTo(...)
Define CTransaction::IsEquivalentTo(const CTransaction& tx)

True if only scriptSigs are different.  In other words, true if
the two transactions are malleability clones.  In other words,
true if the two transactions have the same effect on the
outside universe.

In the wallet, only SyncMetaData for equivalent transactions.
